Worked all day changing all the MAP, TPU, O2, and Intake temp sensors, plugs, rotor, cap, changed the capacitors in the ECU and still have the same symptoms. 4 cyl, 5 speed. Will not crank with the MAP sensor plugged up. With the MAP unplugged, it will crank and run rough until the check engine light comes on. Then it runs OK up to around 4200 RPM. At 4200 it cuts out much like a rev limiter. The error codes are 12, 14 twice, 33, and 15. The check engine light comes on as soon as you turn the key on for a few seconds then goes out whether the MAP is plugged in or not. Checked the power to the MAP and it is OK(4.8V) when unplugged and about 40 mV when plugged in. Have tried 4 different MAP sensors with the same results. Anybody have any suggestions?? Thanks.
